Fedora 20 has hit USB sticks (so to say) and it could be the time to add the "fedora20" (sic) tag.
Reminder: the following tags currently exist.
It's kinda uneven, but indicating the Fedora version is indeed of some interest as the distribution's behaviour may change heavily:
fedora [generic, clearly] fedoracore [the old fedora name] fedora8 fedora9 fedora12 fedora13 [fedora-13 aliased to it] fedora14 fedora15 fedora17 fedora-ds [not for a Fedora Release but for the Fedora Directory Server. Hah!]
For those interested in history:
